Apparatus for thawing oils in receptacles.



I 'TATE PATENT FFIc e FRANCOIS GIORDAN, OF NICE, FRANCE.

SPECIFICATION forming part of Letters Patent No. 651,1 11, dated June 5, 1900.

Application filed January 20, 1900. Serial No. 2,229. (No model.)

To aZZ whom, it may concern.-

Be it known that I, 'FRANQOIS GIORDAN, a citizen of the Republic of France, and a resident of Nice, France, have invented certain new and useful Improvements in Apparatus for Thawing Oils in Receptacles, of which the following is a specification.

The object of my present invention is to provide an apparatus for thawing oils in receptacles adapted to be heated by means of gas, petroleum, or other combustible substances, as hereinafter fully described and claimed.

In the accompanying drawings, forming a portion of this specification, and in which like numerals refer to like parts throughout all the views, Figure l is an elevation of the apparatus dipped into a receptacle filled with oil. Fig. 2 is a vertical central diagrammatic section of the apparatus. Fig. 3 is a horizontal section on line A B of Fig. 1.

Referring to the drawings, 1 represents a metal cylinder, the lower end of which is fitted into a strengthening-socket 18, while the upper end thereof terminates in a funnel 19. Said cylinder 1 contains an inner concentrically-arranged cylinder 2, resting 011 the bottom of cylinder 1 and provided at its lower part with a small cross-bar 10. Two tubes 3 and a are branched on said cylinder 2 at opposite points located under the crossbar 10, said tubes extending through the walls of cylinder 1 and then upward to the upper end of the latter, in which position they are secured by means of collars 11 11, tightened by means of rivets or equivalents 16 16. On the cross-bar 10 is arranged a small support 15, carrying a coiled tube 9, the outer wall of which is perforated and which communicates with a central tube 5. Said coiled tube forms a burner, and the central tube 5, the upper part of which is connected with a horizontal tube, serves to lead gas or its equivalents to the burner. Said horizontal tube has an extension 7 to guide the cen t-ral tube in the cylinder 2. To this end when the tube 5 is lowered into the cylinder 2 said horizontal tube and its extension slide in suitable slots provided in cylinder 2. Said horizontal tube may be connected with a gaspipe by means of a flexible tube 8.

The apparatus operates as follows: It is introduced into the oil-receptacles, as shown in Fig. 1, and the annular space between the cylinders 1 2 is filled with water to fourfifths of its height. Then thefiexible tube 8 is connected to a gas pipe, and the central tube 5, with the burner 9, is withdrawn from the cylinder 2. Then said burner is lighted and again inserted into the cylinder 2, the necessary air being admitted through the tubes 3 and 4 in the direction of the arrows. The water contained in the annular space between the cylinders 1 and 2 is thus heated by the burner and will transmit its heat to the oil'to thaw or liquet'y the latter without any alteration.

Having fully described my invention, what I claim, and desire to secure by Letters Patcut, is

1. An apparatus for thawing oil in receptacles adapted to be heated by means of any desired combustible substances, and comprising an outer cylinder, an inner cylinder arranged concentrically Within the former, the annular space between said cylinders serving to contain water; a central tube the lower end of which is provided with a suitable burner and serving to lead gas or its equivalent to the latter said central tube being adapted to be connected to a suitable feedpipe; and two air-tubes serving to lead air to the burner for the combustion, substantially as set forth.

2. In an apparatus of the class set forth, the combination with an outer cylinder, of an inner cylinder concentrically arranged in the former, a cross-bar secured in the inner cylinder, a burner-tube supported on said crossbar, two tubes branched on said cylinder and extending upward along the outer cylinder, and means for securing said tubes to said outer cylinder, as set forth.

3. In the apparatus of the class set forth the combination with a cylinder 1, a cylinder 2 arranged concentrically in the former, two

tubes 3 and t branched on the inner cylinder gaged by said branch pipe, substantially as and extending upward on the outside of cyland for the purpose set forth. 1o inder 1 and cross-bar 10 secured Within cyl- In testimony whereof I have hereunto set inder 2 of a coiled burner 9, suitably army hand in presence of two Witnesses.
